I have a itouch 2G with firmware version 3.0 and I enabled the bluetooth of it. I downloaded the HP iprint app from Apple store. And I have a HP Photosmart Premium with Fax all-in-one printer(C309A). I also enabled the bluetooth on it. But the itouch bluetooth and the HP printer bluetooh could not detect each other. When I started up the HP iprint from the itouch and selected a picture, the itouch indicated no printer available. The two devices were placed next to each other. What do I need to do to make this work? Thanks.
